Abstract EN
A laboratory experiment was conducted during 2015 and 2016 seasons to improve uptake and productivity of grapevines by producing three newly strains of solubilizing k bacteria(histidineless, argnineless and phenylalanineless) by exposing the wild streptomyces sp.
with different doses of ultraviolet irradiation from one to five minutes.
these newly k strains as well as the slow release k fertilizer feldspar was used as a partial replacement of mineral k namely potassium sulphate (48% k2o).
supplying the vines with k as 50 to 75% mineral k plus feldspar as a slow release k fertilizer at 25 to 50% and any one of the three k bacterial strain each at 5 to 10 ml had an announced promotion on growth characteristics, pigments, n, p, k, mg, ca and s, berry setting (%),yield as well as physical and chemical characteristics of the berries relative to the application of k as mineral k alone.
the best k strain was histidineless followed by phenylalanineless and strain argnineless occupied the last position.
the berries quality was remarkably enhanced due to supplying the vines with k as 50% mineral k + feldspar at 50% + argnineless strain at 10 ml/vine.
for promoting yield of superior grapevines, it is advised to supply the vines with k as 50% inorganic k plus 50% feldspar and histidineless strain at 10 ml/vine.
supplying the vines with k as 25% mineral k+ 75% feldspar + 20 ml (argnineless strain) gave the best results with regard to berries quality.
